Joe: Well you see you get this big end grinder and attach 3-4 buffing pads side by side on it. Get a several large sticks of roughe. Have a garden hose with a fine mist spray for temperature control. When you get it all set up you drive by Home Depot in the AM and pick up two of the strongest looking workers standing out front, take them home. After giving instructions on polishing get your lounge chair and a six pack. Before you know it the bus will be polished. This operation is best done out of site of the light green trucks with the badges on the doors. Good luck and stay out of the sun.
If the job runs into a twelve or twenty four pack, you chose the wrong crew.
